Rhine concentrates on the ""middle sized"" soil animals from mites and ticks to earthworms, and though it's true that it's hard to say much that's new about worms, ants, and beetles, he manages to sharpen the survey with some interesting and little-known tidbits: why the swarming spring tail (most numerous among the soil animals) bleeds before he is attacked, why Darwin's earthworms fled when he played low notes on the piano, why ants lick each other constantly and how they deal with foreign queens who assassinate their own matriarch. Attractively serviceable illustrations and directions for making devices in which to catch and raise soil animals are further pluses.
